Sorry, have been out of UK and only just seen this one. Have lived 20+ years nearby and am not aware of any use by fixed wing - tho if I got engine failure in circuit at Blackbushe it might get a visit ! Only ever seen it used by mil helicopters and very rarely at that. Last time about 3/4 years ago when the runway was stengthened tempo by steel mesh. The white Xs have mostly weathered away now and the surface is more lose gravel than hard. Also the surrounding trees are now markedly higher than when I first came across it. Not a beginners strip therefore ! I believe a recent 1/500000 chart had it marked but it has not been repeated.
